Warp in, 5 groups. Once dealing with the instant aggro from group 1 the remaining groups are at extreme range. All ships may aggro on attacking any one ship. Ships may also switch target to aggro drones if drones attack the sentries. The Tower Sentries are proximity activated and will aggro as soon as you get within 80km, so going for one of the middle ones will possibly put you in range of 2 others. Tower Sentries range is limited to 80km.
